 # Introduction
 There will have two parts in this repo
- * AsyncSignal class specially designed to distinguish async method.

 ## AsyncSignal

 # Conclude
- The essential part is to overwrite a new async method. Another way would be to generate a new method with a different name, for example, `sayHiAsync`, then we can get rid of `AsyncSignal`. But there's an obvious flaw of this way, that is, all method level configurators and routers defined to `sayHi` will not take effect.
